- convert decimal record to floating-point value
#include <floatingpoint.h>voiddecimal_to_single(single *px,decimal_mode *pm,decimal_record *pd,fp_exception_field_type *ps);
voiddecimal_to_double(double *px,decimal_mode *pm,decimal_record *pd,fp_exception_field_type *ps);
voiddecimal_to_extended(extended *px,decimal_mode *pm,decimal_record *pd,fp_exception_field_type *ps);
voiddecimal_to_quadruple(quadruple *px,decimal_mode *pm,decimal_record *pd,fp_exception_field_type *ps);
These functions convert the decimal record *pd to a floating-point value *pxobserving the rounding direction specified in *pm and setting *ps to reflectany floating-point exceptions that occur.
Whenpd->fpclass isfp_zero,fp_infinity,fp_quiet, orfp_signaling, *px is set tozero, infinity, a quiet NaN, or a signaling NaN, respectively, with the signindicated bypd->sign. All other fields in *pd are ignored.
Whenpd->fpclass isfp_normal orfp_subnormal,pd->ds must contain a null-terminated stringof one or more ASCII digits representing a non-zero integerm, andpd->ndigitsmust be equal to the length of this string. Then *px isset to a correctly rounded approximation to
-1**(pd->sign) * m * 10**(pd->exponent)
pd->more can be set to a non-zero value to indicate that insignificanttrailing digits were omitted frompd->ds. In this case,m is replacedbym +delta in the expression above, wheredelta is sometiny positive fraction.
The converted value is rounded according to the rounding direction specified inpm->rd.pm->df andpm->ndigits are not used.
On exit, *ps contains a bitwise OR of flags corresponding to anyfloating-point exceptions that occurred. The only possible exceptions are underflow, overflow, andinexact. If no floating-point exceptions occurred, *ps is set to zero.
